My make knowledge is very very limited, so if there's a better way to do
this please let me know! This seems to work and lets me cut one off
builds easily.
The `hc-install` tool we're using needed a patch for a specific bug, but that's
since been merged. We definitely want to switch to using a standard release from
that project once one is shipped with the CLI, but pinning to HEAD should keep
us for now.
* client: protect user lookups with global lock
This PR updates Nomad client to always do user lookups while holding
a global process lock. This is to prevent concurrency unsafe implementations
of NSS, but still enabling NSS lookups of users (i.e. cannot not use osusergo).
* cl: add cl
The ec2info was never intuitive to run - needing to set the AWS
envinronment variables, cd'ing into tools/ec2info, and knowing
to invoke the command.
This PR makes it so we can run ec2info just by running
make ec2info
The command now also checks for the AWS environment variables being
set, and provides a useful error if they are not.
This PR activates the osuergo build tag in GNUMakefile. This forces the os/user
package to be compiled without CGO. Doing so seems to resolve a race condition
in getpwnam_r that causes alloc creation to hang or panic on `user.Lookup("nobody")`.
This PR update to Go 1.18.2. Also update the versions of hclfmt
and go-hclogfmt which includes newer dependencies necessary for dealing
with go1.18.
The hcl v2 branch is now 'nomad-v2.9.1+tweaks2', to include a fix for
newer macOS versions: 8927e75e82
test_checks.sh was removed in 2019 and now just breaks if VERBOSE is
set when running tests via make targets
in GHA, use verbose mode to display what tests are running
Part 2 of breaking up https://github.com/hashicorp/nomad/pull/12255
This PR makes it so gotestsum is invoked only in CircleCI. Also the
HCLogger(t) is plumbed more correctly in TestServer and TestAgent so
that they respect NOMAD_TEST_LOG_LEVEL.
The reason for these is we'll want to disable logging in GHA,
where spamming the disk with logs really drags performance.
This PR updates GNUMakefile to respect $GOBIN if it is set in the
environment or via an $GOENV file. Previously we hard-coded the output
to $GOPATH/bin, which is not necessarily the desired behavior.
Since switching to `golangci-lint` we have set the `-j 1` flag, which
restricts the tool to using 1 CPU thread.
This PR removes the flag so `make check` takes less time on good
computers.
This PR upgrades our CI images and fixes some affected tests.
- upgrade go-machine-image to premade latest ubuntu LTS (ubuntu-2004:202111-02)
- eliminate go-machine-recent-image (no longer necessary)
- manage GOPATH in GNUMakefile (see https://discuss.circleci.com/t/gopath-is-set-to-multiple-directories/7174)
- fix tcp dial error check (message seems to be OS specific)
- spot check values measured instead of specifically 'RSS' (rss no longer reported in cgroups v2)
- use safe MkdirTemp for generating tmpfiles
NOT applied: (too flakey)
- eliminate setting GOMAXPROCS=1 (build tools were also affected by this setting)
- upgrade resource type for all imanges to large (2C -> 4C)

Meant for development purposes only, so one can compile binary on a
macos host then start a Docker container or scp the binary to a linux
host easily.
The resulting binary is statically linked and has very subtle
differences. e.g. static binaries use go native network stack that
honor /etc/hosts and /etc/resolve differently from the glibc
implementation. In development environment, I don't expect these to
materially change our experience.
